How should I approach this girl?

Hi, there is a girl i like for quite a while, she is the most beautiful girl i have ever seen, i train taekwondo and so does she, but in another town, i had some chances to approach, she was standing right next to me, but i couldn't do it, i don't know what to say, and i think i will start saying stupid things

Couple of months ago, she won a Paralympic bronth medal, so i was thinking about bringing it up, but i don't know exactly how or what to follow up with

Since she won Paralympics, she got quite a famous and i know there are a lots of guys texting her, i think there is no point to start with texting and i have to approach in person

I have never had a relationship with girl, so i am quite an inexperienced, she is 19 years old i am 18.

I was also thinking that i would only approach her if i won competition myself and feel worthy, but i think there is no time to waste, what do you think i should do?

How should I approach this girl?
